Vibration insulated tables LTH

The Bilz laboratory table LTH is a vibration insulated work place and can be used for all applications where vibrations and/or changes in level cause sustained disturbances to the experiment or work. Disturbing vibrations from the environment are isolated by means of highly effective membrane air spring insulators and the solid hard stone plate. At the same time the mechanical-pneumatic level control automatically ensures that the level is retained to an accuracy of up to ±1/100 mm even with load changes. The maintenance unit for compressed-air conditioning is included.

LTH – Insulated tables with BiAir® OC

OC = one chamber

Due to their increased air volume the newly-developed BiAir® OC air springs achieve a reduced natural frequency of approximately 2 Hz in the vertical plane. The laboratory tables with BiAir®OC air springs are suitable for applications with lower dynamics that require an excellent insulation effect.

LTH – Insulated tables with BiAir® PAS

PAS = pendulum air spring

Newly developed pendulum suspended BiAir® PAS air springs achieve a reduced vertical natural frequency due to their increased air volume and also have reduced natural frequency in the horizontal plane due to their pendulum suspension arrangement. This enables the laboratory table with pendulum air springs to reach a natural frequency of approximately 2 Hz in the vertical plane and approximately 1.2 Hz in the horizontal plane. The laboratory table with pendulum air springs is suitable for applications with low dynamics and higher requirements for vibration insulation in both the vertical and horizontal planes.
